After a hiatus, I'm back in the darkroom, with the lights on and reworking some black and white prints.
I've using the two bath process of potassium ferricyanide and hypo solution. The trade name for the product is Farmers Reducer and it's available from Silverprint in London.
The aim is to brighten over developed prints by adding sparkle and subtle shades of cream.
This technique works best on prints that are not too contrasty and have an even range of tones. The effect is noticeable after 5-8 seconds; this is my average time of use.
Be careful with prints that have pale or under developed areas. Skyline and clouds are liable to disappear off the silver horizon. There is also the risk of staining depending upon how you had previously fixed and washed your print.
If you have multiple prints of an image, then this is a good technique to practice in the light of a darkroom. Keep a master untreated for future reference.
Practice almost makes perfect.
However nothing beats getting the exposure correct in camera. This means registering a good range of black and white tones, the highs and the lows.
Practice can then make perfect.
